Description

The liquid analysers EXPERT-001 are designed for measurement of ionic activity index (pH, pH), electromotive force (EMF) of electrode systems (in particular, redox potential (Eh)), temperature and mass concentration of dissolved oxygen in water, aqueous and some non-aqueous media.The analysers can be used in the determination of biochemical oxygen demand (BOD), potentiometric titration and other potentiometric and amperometric measurements according to appropriate measurement procedures.
